Aeromarine Sprint Cat .80/.90 twin 1717's

[millzee]

I've also thrown heaps at the 1717's in a few boats and in cars/trucks and agree on that, I love these motors. I had a little set back on the build yesterday. While setting up the flex drives I stuffed the only reverse rotation shaft I have and now I'll have to wait until the replacement arrives. I had cut it to length but hadn't bothered to solder the end as of yet and upon entry to the coupler, one loose wire caught and began to unwind the others, all I'll say is, I now have a soldered flex thats about 1/2" too short. I won't do that agian, the boat was ready for it's maiden on Sunday, DOH!!

that is very good to know!thanks

Yeah man they are a great motor for sport running I only have good to say about them

[Brushless55]

Any time I ran a single 1717 or twin 1717 they always came back cold as hell no matter what prop I threw at them.

that is very good to know!

Ooops my bad I thought you were using the t180,s.

[millzee]

especially on a set up using 1717 and a 180 esc.

The water cooling lines do look a tad confusing, the pic didn't show the 4x outlets, 2 on each side coming from each motor and esc. I'll add a couple more pic's showing the brass water pic ups I've made, I'm a little unsure how they'll go so I've ran those to the motors and the dual rudder pick ups to the esc's.

[grsboats]

Sweet!

[kendt]

LOl if you say so. I personally dont think those esc,s are the best choice for those motors but hey,Time will tell.

[Rumdog]

Meh.. He'll be just fine

[kendt]

It looks awesome. It will fly. I cant tell from the pics, are you using the same water to cool the esc,s and the motors? Personally i would never do this, especially on a set up using 1717 and a 180 esc. Those motors can pull some pretty serious amps. I always run a separate water supply line to the esc and motor. Most lakes and ponds in the peak of summer are not all that cool to begin with. Worth the extra work to make sure everything is getting cooled as best as possible.Its an awefull nice build. Hate to see anything going up in smoke!!

[millzee]

The water coolings now done and to power the rx ect. I've fitted a 3000mAh losi NiMH into the front right sponson that connects to an on/off switch into the rx. The rudder is ready to go with plenty of tourque from a hitec 7955, I'll keep doing more work this week.

[millzee]

I have the hatch done and working on the rest today, If I don't get interrupted too often, I may finaly get this thing on the water next weekend.

[millzee]

I will line the cowl with carbon/kevlar and have bolts holding it on along with some foam on the rim and tape on the outer.

[KartRacer]

Watching with interest! Have you decided what you will do with the cowl?
